reel, I have simply for illustration cable onto a cable reel on anelectric locomotive. It is principally adapted for use in connectionwith horizontally mounted cable reels and is adapted to direct the cableonto the reel from either side thereof in accordance with which end ofthe locomotive the cable has been paid off from.

For the purposes of illustration I have shown my mechanism applied to acable reel on an electric locomotive of the type now generally used inmine work.

Figure 1 is a side elevation of a locomotive provided with a cablespooling and guiding mechanism embodying my improvements. Fig. 2 is aplan view of the same. Figs. 3 to 4 show details.

In the drawings 1 indicates as an entirety an electric locomotive, 2 anelectric motor for propelling the locomotive, and 3 indicates a cablereel mounted horizontally at one end of the locomotive. This reel ispreferably carried by a reel shaft 3 which is mounted at either end inbearings 3 3 in standards 4, 4: on a reel carrying frame f which issecured to the locomotive frame.

The power for operating the reel may be applied thereto in any suitableand well known manner. A separate motor than the one used for propellingthe locomotive may .be used, or a train of power transmitting devicesmay be interposed between a locomotive motor and the reel in any desiredmanner. As this invention does not relate to the manner of and means fordriving the urposes shown an electric motor 5 secured to the locomotiveframe, adapted onlyfor driving the reel and connected thereto by powertransmitting devices indicated as an entirety by 5. The electricalconnections to this motor and the propelling motor on the car are notshown, as it is understood that my in vention relates only to the cablespooling and guiding mechanism now to be described and that consequentlyany well known and suitable reeling mechanism and means for operatingand controlling the reeling mechanism may be employed.

The mechanism for s ooling and uiding the cable onto the rec isindicatef as an entirety by 6. Of this mechanism 6 6* indicate armsloosely mounted. on the reel shaft,-each one preferably being adjacentto one of the standards 4 At their outer ends each of these arms carriesa bearin block or plate 6". 7 is a double threade shaft arranged arallelto the reel shaft and mounted at eit er end in bearings in the adjacentbearing blocks 6*. This double threaded shaft extends through one of thebearing blocks 6' at one end of the reel and has secured to it asprocket wheel 8. 9 is a sprocket wheel arranged in alinement with thesprocket wheel 8 and rigidly secured to the reel shaft. 10 is a drivingchain connecting the sprockets 8 and 9. 11 indicates as an entirety atraveler adapted to travel to and fro along said double threaded shaftas it is rotated by the reel shaft. This traveler comprises a frame 11'arran ed to carry within it a pair of longitu inally mounted rollers 11and a pair of transversely mounted rollers 11. The rollers of each ofthese pairs of rollers are adapted to receive between them and to guidethe cable 12. At one end and on opposite sides this cable guide framehas transversely extending ribs 11 which are adapted. .to engage withthe walls of grooves 13 in traveler uides 13, which are arranged ateither si e of the traveler and have their ends carried by and securedto the bearing blocks 6". 1a is a follower stud pivotally mounted in thecable uide frame 11 and having a projection a apted to engage the wallsof the threads on the double threaded shaft and to direct the travelerframe to and fro along said shaft in the well known manner.

When the cable is to be paid off from and wound up on the reel from theend of the locomotive on which the reel is located, it is desirable tohave the cable spooling and guiding mechanism arranged as shown in fulllines in Fig. 1 so that the traveler 11 for guiding the cable onto thereel will be in front of the reel as it moves toward the paid out cable.To hold the cable spooling Office by N. A. Newdick.

and guiding mechanism in this position I have provided brackets 15arranged at either end of the reel supporting structure, each secured toan adjacent standard 4. and each adapted to be engaged by and to supportone of the bearing plates 6".

When it is necessary to pay out and reel up the cable from the operatorsend of the locomotive, the cable spooling and guiding mechanism may beswung to the position indicated in dotted lines in Fig. l, in which casethe cable guiding traveler is still in front of the reel when thedirection of travel of the reel is considered. For maintaining thespooling and guiding mechanism in this position I have providedbrackets16, each arranged at one end of the reel supporting frame, each securedto the adjacent standard 4 and each adapted to be engaged by and supportone of the bearing plates 6".

The transversely arranged guiding and supporting rollers carried by thetraveler frame 11 are so arranged that one of them will support theflexlble cable when the spooling and guiding mechanism is in oneposition of ad ustment, while the other will support the cable when thesaid mechanism is in its other position.

I believe thatI am the first to devise a cable spooling and guidingmechanism for a cable reel on an electric locomotive whichmechanism iscapable of adjustment into various positions relative to the reel inorder to facilitate the reeling and spoolin of the cable on the reelirrespective of w ich side of the reel is in advance as the reel movestoward the paid out cable. Very often it is desirable to pay off thecable from the operators end of the locomotive rather than from the reelend thereof, and consequently the importance of my invention will atonce manifest itself, since under such circumstances it is essential tothe proper guiding and spooling of the cable that it be directed ontothe reel from a point other than i that necessary to properly guide itand spool it'when the cable is paid off from the reel end of thelocomotive.

I have shown in this application an arrangement of reel drivingmechanism and friction clutch mechanism and brake device which I haveclaimed in my application Ser. No. 194,590, Renewal No. 479,515.

I am not the inventor of the independent electric drive for the cablereel or of the worm gearing in the power transmitting devices foroperatin the reels which are shown and describe in this application, andI understand that application, Ser. No. 289,640 upon these features ofconstruction has been filed in the United States Patent What I claimis 1.

2. In a cable reelmg mechanism for an electric locomotive, thecombination with a cable reel mounted on a transverse horizon tal axisand means for o erating it, of a cable spooling and guiding mechanismmounted to swing about the axis of the reel and to be supported in aposition in front of the reel or in a position behind the reel andcomprising a double threaded shaft parallel to the reeling axis, and afollower adapted to travel along said shaft, and power transmittinggearin positively connecting the reel and the said shaft irrespective ofthe position of adjustment of the cable spooling and iding mechanism.

3. n a cable reeling mechanism for an frame in a position in front ofthe reel,
